Title: Improvements in or relating to electrical delay networks
IPC: H03H7/01
Filed: 1954-12-22
Abstract: 770,878. Delay networks. INDJOUDJIAN, M. D. Dec. 22, 1954 [Dec. 22, 1953; March 3, 1954], No. 37073/54. Drawings to Specification. Class 40 (8). A ladder-type delay network to be inserted between input and output resistances R 1'  R 2  comprises a total number n or series inductors and shunt capacitors and has a delay time # independent of frequency, the values of the network elements being such that for any value f = #/ 2 # of the input frequency the transfer function of the network is (1 + p/n)<SP>n</SP> where p = j##. When the network is inserted between a voltage source of internal resistance R 1  and a load R 2 , the transfer function T (p) is defined by the ratio in which Ee<SP>pt</SP> is the input E.M.F. and Ue<SP>pt</SP> the output voltage, E and U being complex. When R 2  is infinite the transfer function T(p) is E/U and when R 1  is a current source of infinite internal impedance the transfer function is R 2 I/U where I is the input current. If n is increased to infinity and the network becomes an ideal network in which all frequencies are delayed without distortion by a time #. By increasing n ideal conditions may be approached. The networks of the invention are non-iterative structures in which the number n of elements necessary to approximate ideal conditions is reduced. The values of the reactances of the inductors and capacitors at an angular frequency # 0  = <SP>1</SP>/# taking R 1  the resistance of the generator as unit impedance are calculated by expressing the input or output impedance of the network in terms of a continuous fraction in terms of the variable p, the coefficients of p giving the values of the reactances. From these reactances the values of the elements are found. The Specification gives a detailed mathematical account of this method and tables of values for actual networks.

IPC: H04N5/225
Filed: 1960-11-03
Abstract: 934,760. Photo-electric control systems. PYE Ltd. Nov. 3, 1961 [Nov. 3, 1960], No. 37842/60. Class 40 (3). In order to protect the light sensitive surface of a television camera 2 from damage due to exposure to strong light from the sun or other sources, a roller blind shutter carried by spools 6 and 17 is normally driven by a motor 9 so as to position a viewing aperture 3 in front of the camera lens, but is rapidly rewound on spool 6 under the action of spring 7, so as to cover the lens, when a normally energized solenoid 10 is de-energized to allow a spring 12 to disengage a dog clutch in the drive to spool 17, the deenergization of the solenoid being effected by a signal from a photo-electric P1 or P2 which is responsive to light above a predetermined intensity and has an angle of view greater than that of the camera lens so that it detects strong light before it falls within the field of view of the camera. When the strong light is removed from the field of view, solenoid 10 is re-energized to re-engage clutch 11, whereupon motor 9 restores aperture 3 in front of the lens. A switch 51 operated by a cam 8 on the shaft of spool 17 breaks the circuit of motor 9 when the blind is positioned with the aperture in front of the lens. To allow for the use of lenses with different angles of view, a switch 52 operated by the lens turret is arranged to connect a photo-electric cell P1, P2 of corresponding appropriate angle of view. In a second embodiment, Fig. 3 (not shown), the solenoid is arranged to control the positioning of the roller blind shutter directly, the motor being dispensed with. In a third embodiment, Fig. 4 (not shown), the shutter merely comprises a pivoted plate which is urged by a spring so as normally to cover the lens and which is pivoted to one side when the solenoid is energized. The protective arrangement may be constructed as an integral part of a television camera or may be incorporated in a weatherproof protective housing within which any camera may be used. Where a camera having a zoom lens is used, the photo-electric cell may be provided with an optical system having an adjustable field of view which is operated with the mechanism controlling the zoom lens.
